DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a jewel formed from a plurality of component elements of which at least one is interchangeable.
In general, a jewel consists of a single element formed by a material or an assembly of a plurality of materials of different appearances, and it may or it may not have a movable part for making it easier to fit in it. Convertible jewels consisting of a set of elements are also known, for example a tiara convertible into a necklace by subtracting a particular number of elements, each of which is a jewel, another example being a necklace pendant which can be detached to become a garment lapel brooch.
The object of the present invention is to provide a jewel of variable appearance.
According to the invention, this object is achieved with a jewel composed of a plurality of elements, of which at least one is interchangeable, allowing a change of appearance of the jewel as a whole. According to the invention, the jewel comprises at least two mutually complementary elements, one forming a base and the other an insert, both being of curved form and at least one not being closed on itself. The base has at least one aperture passing through the base from the concave side to the convex side, and the insert has at least one protuberance complementary to the aperture of the base, so that assembling the two elements together as a result of the penetration of the protuberance of the insert into the aperture of the base requires a slight elastic deformation of at least one of the two elements.
According to a preferred embodiment of the invention, the jewel is composed of two elements: a base and an insert. The insert is of a width smaller than that of the base and has protuberances along the curvature on its convex surface; moreover, it has an open form, that is to say it is not closed on itself. The base has at least one aperture, the orifice of which is larger than the maximum cross-section of the insert, so that the latter can be introduced through this aperture from the convex side of the base to the concave side before it is assembled with this. The assembling and dismantling of these two elements are carried out by means of a slight pressure on the insert and the base. The insert or the base can therefore be replaced by another equivalent element having another appearance, in order to change the appearance of the jewel as a whole.
Another preferred embodiment of the invention is a jewel composed of a base having a plurality of rows of apertures distributed over the width, and an equivalent number of inserts of a width smaller than that of the row of corresponding apertures. This makes it possible to vary the appearance of the jewel even more, since the combination of the various inserts and the base can be influenced.
This type of jewel has a definite advantage over conventional jewels. The present invention, as a result of the easy substitution of at least one of the component elements, makes it possible to provide a jewel of an appearance variable according to the particular circumstances of use, making it possible, for example, to adapt the jewel to the particular style of dress by selecting the different geometrical forms, materials, structures, colors, etc. of the interchangeable part or parts.
Other characteristics and advantages of the invention will emerge more clearly from the following description given purely as an illustration and in a nonlimiting way. The description refers to the accompanying drawings in which:
FIG. 1 shows a front view of a bracelet according to the invention;
FIG. 2 shows a side view of the separate base and insert of the bracelet of FIG. 1;
FIG. 3 shows a front view of the bracelet of FIG. 1, with the insert partially introduced into one of the apertures of the base;
FIG. 4 shows a front view of the bracelet of FIG. 3, with the insert in position before it is assembled with the base;
FIG. 5 shows a front view of an ear-clip with the insert partially introduced into one of the apertures of the base; and
FIG. 6 shows a front view of the ear-clip of FIG. 5,
